How to Repair Acer Aspire One A110 Computer LCD Screen

This article covers the repair for a relatively common problem with computer monitor, where the monitor will turn on, but only display a screen for about half a second. Shining a bright light source onto the screen will reveal that the image is there, but the backlight is off. Two capacitors in the power supply have gone bad. Anyone with basic soldering skills should be able to perform this repair, and the cost is quite literally a fraction of buying a new monitor. But buying a new one can save more time.

The cable screw that needs to be removed is circled in red.Remove the back cover and metal shroud under it. There are a number of screws around the outer edge of the back cover. Once you remove those, you'll need to gently pry around the edges of the cover with the flat screwdriver to pop it off. Once you have he back cover removed, you will see a metal shroud covering the electronics. There are a few screws holding Acer Aspire One A110 down as well. Remove the screws and then slide the shroud slightly to the right to remove it. NOTE: There is a black cable running from the monitor's control panel into the shrouded area. You'll need to remove the small screw grounding it to the monitor chassis to unplug it from the circuit board under the shroud.

The two capacitors needing replacement are circled in red.Locate the bad capacitors. There are two, both on the main (left-side, tan) power supply circuit board. There is a yellow transformer near the top of the board; one of the capacitors will be above it, and the other will be slightly to its left.

You should have enough solder still on the board to re-attach the new capacitors; if not, you can use a little more solder. Remember, when replacing capacitors, always use the same microfarad value and the same or higher voltage. I replaced the 1,000 mfd 16v capacitor with a 1,000 mfd 35v one in my monitor with no problems. Be sure to install the capacitors with the correct polarity, just as you would with a battery. The wide gray or white band on a capacitor is the negative side. The positive side is marked on the board.Replace the Acer Aspire One A110 power supply board, metal shroud and back cover. Make sure that when you replace the board, the two connectors attach to the video board.
